According to the hydrological data and the water quality samples and analyses item of Yong-Ann watershed: Suspended Solids（SS）, Total Phosphorous（TP）and Ammonia Nitrogen（NH3-N）result of analysing, show that the concentration of water quality of rainstorm is mostly higher than the concentration of water quality of the sunny day, and the concentration of SS , TP and NH3-N is apt to be higher than the class-A water body water quality standard, so set up structural BMPs facilities for the clear decision of Feitsui Reservoir Administration in the downstream place of Yong-Ann watershed. Learn after making up with structural BMPs of three kinds of schemes of MUSIC simulation, scheme one（grassed swales=> upper vegetated buffer strips=> lower vegetated buffer strips=> detention basins）, scheme two（detention basins=> upper vegetated buffer strips=> lower vegetated buffer strips=> grassed swales）and scheme three（upper vegetated buffer strips=> lower vegetated buffer strips=> grassed swales=> detention basins）treated concentration of water quality, all smaller than the class-A water body water quality standard, among them, the best with getting rid of the result of scheme one. It is the important water quality protection zone of source of water in the Feitsui Reservoir watershed, Do a good job of nonpoint source pollution cuts down facilities can have demonstrate, propaganda and technology popularization function. This BMPs demonstration area proves that structural BMPs facilities have suitable getting rid of the efficiency to nonpoint source pollution, if utilize MUSIC to assess structural BMPs and set up priority, and then popularize from small-scale structural BMPs demonstration area to the comprehensive implementation of the reservoir watershed, can reach the improved goal of water quality.
